sh: lib: convert to SPDX identifiers

2018-12-28T20:11:45+00:00

Update license to use SPDX-License-Identifier instead of verbose license text.

sh: ftrace: Remove check of obsolete variable function_trace_stop

2014-07-18T17:57:04+00:00

Nothing sets function_trace_stop to disable function tracing anymore. Remove the check for it in the arch code. [ Please test this on your arch ] Cc: Matt Fleming Cc: Paul Mundt Signed-off-by: Steven Rostedt

sh: Fix up stack debugging build.

2013-01-14T09:07:36+00:00

Somewhere along the line the ebss label was taken out, resulting in pcrel branch too far errors. Restore the label to get things building again. Signed-off-by: Paul Mundt

mtd/uclinux: Use generic __bss_stop instead of _ebss

2012-06-27T07:59:43+00:00

The standard (see BSS_SECTION() in and ) symbol for the end of BSS is __bss_stop. This allows to remove all local declarations that have been added to several architectures just to please CONFIG_MTD_UCLINUX.

sh: Fix up stack overflow check with ftrace disabled.

2009-07-11T12:06:53+00:00

Presently the STACK_CHECK() code is called in to multiple times, although it's only necessary from the mcount entry. The code still attempts to treat the nop case as an ftrace path resulting in superfluous code flow for the case where ftrace is disabled. And finally, this also fixes up references to a few undefined symbols when FUNCTION_TRACER=n. Signed-off-by: Paul Mundt

sh: Fix up ftrace build error when STACK_DEBUG=n.

2009-07-11T11:33:34+00:00

Presently the closest reference to function_trace_stop is within a CONFIG_STACK_DEBUG block. When this is turned off, the build bails out with a pcrel too far error. Reorder things a bit to handle the various combinations. Signed-off-by: Paul Mundt

sh: Function graph tracer support

2009-07-11T01:08:01+00:00

Add both dynamic and static function graph tracer support for sh. Signed-off-by: Matt Fleming Signed-off-by: Paul Mundt

sh: Provide diagnostic kernel stack checks

2009-07-11T01:07:58+00:00

Enable kernel stack checking code in both the dynamic ftrace and mcount code paths. Check the stack to see if it's overflowing and make sure that the stack pointer contains an address that's either in init_stack or after the bss. Signed-off-by: Matt Fleming Signed-off-by: Paul Mundt

sh: Add ftrace syscall tracing support

2009-07-06T11:16:33+00:00

Now that I've added TIF_SYSCALL_FTRACE the thread flags do not fit into a single byte any more. Code testing them now needs to be aware of the upper and lower bytes. Signed-off-by: Matt Fleming Signed-off-by: Paul Mundt

sh: Define HAVE_FUNCTION_TRACE_MCOUNT_TEST

2009-07-06T10:53:53+00:00

Enable HAVE_FUNCTION_TRACE_MCOUNT_TEST and test the value of function_trace_stop from our assembly code as opposed to using the generic C function. This should optimise our mcount/ftrace code path. Signed-off-by: Matt Fleming Signed-off-by: Paul Mundt
